Abstract

It is an object to provide an examinee-in-vivo insertion device and an examinee-in-vivo information acquisition system with the examinee-in-vivo insertion device that can increase a frame rate without having a compression function. A capsule type endoscope (2) converts a transfer processing rate (F2) of a signal processing unit (23) into a higher rate. The signal processing unit (23) reads out anexaminee-in-vivo image on a pixel basis from a memory (232) that temporarily stores the examinee-in-vivo image, converts it into serial data (Ss), and transfers the serial data (Ss) at the transfer processing rate (F2), while the higher rate is higher than a rate (F1) at which the examinee-in-vivo image picked up by an image picking-up unit (22) is written at the memory (232). This arrangement shortens a period of time taken from the picking-up of the examinee-in-vivo image to the transmission of the picked-up image to the outside by wireless and makes a picking-up interval by the picking-up unit (22) short, thereby making it possible to increase a frame rate.

Description

technical field

[0001] The present invention relates to a body-introduction device for acquiring images in a body of a body and a system for obtaining information in a body of a body. Background technique

[0002] In recent years, in the field of endoscopes, a swallowable capsule endoscope has been developed. This capsule endoscope has an imaging function such as an image sensor and a wireless function, and has a function of swallowing the capsule endoscope from the patient's mouth for observing the inside of the body cavity until it is naturally discharged from the human body. During this period, the capsule endoscope moves along with the peristaltic motion inside organs such as the esophagus, stomach, and small intestine, and takes pictures sequentially (for example, refer to Patent Document 1 and Patent Document 2). In addition, the image data captured by the capsule endoscope inside the body while the capsule endoscope is moving in the body cavity is sequentially transm...
